Why the Bay Area Chooses Gadi Construction
I engaged GADI Constructions Inc to restore my unit in a high rise in San Jose. Right from the beginning Millie, Project Manager, was very professional and when entrusted with the job completed the repair and restoration work smoothly and in time with perfection with time to time progress reporting on phone and through video.
We explored a home addition for our growing family and these folks handled everything with a lot of thought. The builders explained the remodel plan clearly and made the space blend into the house naturally. It was a solid experience all around.
We recently engaged Gadi Construction for a home renovation project, and the experience exceeded our expectations. Their team demonstrated exceptional flexibility, efficiency, and accommodation, adapting seamlessly to our evolving needs while maintaining a high standard of workmanship. The quality of the final output was impressive, reflecting meticulous attention to detail. Millie, our dedicated project manager, along with her team including Mike, fostered a reassuring and collaborative environment throughout the process, ensuring clear communication and minimal disruption. We highly recommend Gadi Construction for any renovation endeavors; their professionalism and commitment to client satisfaction are commendable.

We worked with Nadav from Gadi Construction during the planning phase of our expansion project, and he was a fantastic advisor throughout the process. He helped us think through every detail — from design implications to quality considerations — and brought a thoughtful, thorough, and methodical approach to each discussion.
Nadav was always friendly, highly professional, and incredibly responsive. It consistently felt like he was acting as a truly independent advisor who cared deeply about building long-term relationships and making sure we would get the very best outcome for our project. His proposals were detailed, insightful, and clearly grounded in deep experience.
Although we ultimately moved forward with another contractor who came through a personal referral, that decision wasn’t a reflection on Nadav’s work or professionalism. Based on our experience, we’d be thrilled to work with him in the future and wholeheartedly recommend him to anyone looking for a trusted, high-quality construction partner.
I went with them for a kitchen makeover and it was worth every penny. The design team helped me see options I never thought about.
Their skilled builders were respectful of the house and kept everything tidy. It felt like a real partnership through the whole remodel.
The value added by the new layout is already noticeable. I still walk in and smile because the remodel turned out exactly right.
Taking on a whole house renovation sounded stressful but they took the edge off. They walked us through each stage of the project so we always knew what was happening. The result feels like a true custom home remodeling job.
The bathroom remodel completely changed how our space feels. Their team helped plan everything so the design made sense and looked great. The quality build is obvious in every corner. It’s nice to have a space that’s functional and adds value at the same time.
We worked with this business for a full residential remodel, and it was a great experience. The skilled builders brought the design to life exactly as we imagined. Every room feels intentional and high-quality. I’d happily recommend them to anyone looking for a thoughtful and professional remodel.

The cost of a 20x20 room addition in California varies widely based on location, materials, and complexity. A basic, single-story addition typically starts around $80,000 to $120,000. For mid-range finishes or a second-story addition, expect $120,000 to $200,000. High-end custom projects can exceed $250,000. Key cost factors include site preparation, foundation work, roofing, plumbing, electrical, HVAC, and interior finishes. California's strict building codes, high permit fees, and labor costs significantly influence the price. It is crucial to obtain multiple detailed quotes from licensed contractors and budget for a 10-20% contingency for unforeseen expenses during construction.
The 30% rule for renovations is a common budgeting guideline suggesting you should not spend more than 30% of your property's current market value on a major renovation project. This is a rule of thumb to help homeowners avoid overcapitalizing—where the cost of improvements exceeds the value they add to the home, making it difficult to recoup the investment upon sale. For example, if your home is worth $500,000, your renovation budget under this rule would be capped at approximately $150,000. It's a starting point for financial planning, but actual budgets should be tailored based on the project scope, local market conditions, and your long-term goals for the property. Always consult with a professional appraiser or contractor for a precise assessment.
The cost comparison between building new and adding an addition depends heavily on your specific project and location. Generally, a well-planned addition can be cheaper than new construction, as you're leveraging existing foundations, utilities, and structure. However, additions often involve complex integration with the old building, potentially uncovering unforeseen issues like outdated wiring or structural problems, which can increase costs. New construction typically offers more predictable pricing and avoids the constraints of an existing footprint. For a definitive answer, obtain detailed quotes for both scenarios. A key factor is your property's value; a major addition should align with neighborhood home values to ensure a good return on investment.
The most expensive part of a home addition is typically the structural work and foundation. This includes excavation, pouring a new concrete foundation or slab, and constructing load-bearing walls and a new roof structure. These elements require significant labor, materials, and engineering to ensure the addition is safe, level, and properly integrated with the existing house. Following this, high-cost items are usually the roofing, exterior siding, and major system extensions like HVAC, plumbing, and electrical. While finishes like kitchens or bathrooms have high per-square-foot costs, the foundational and structural phase forms the substantial, non-negotiable base cost of the project.
